Clone doesn't look right

[natxx]

Title says it all basically.
This happened in a modpack but I tested it with only sync and the same thing happened.
It looks kinda bigger and has steve arms instead of alex arms.
The arms are also sort of bulging out the sides of the glass.
Also the hat layer of the skin doesn't work for clones that I've put in storage
